### To reproduce
1. Include a code snippet that is as short as possible
2. Specify the command which should be used to compile the program
3. Specify the command which should be used to launch the program
4. Indicate what is wrong and what was expected
### Environment
- OS: [e.g Windows/Linux]
- Target device and vendor: [e.g. Intel GPU]
- DPC++ version: [e.g. commit hash or output of `clang++ --version`]
- Dependencies version: [e.g. the output of `sycl-ls --verbose`]

Research direction
Start with the Windows DX12 interop job linked in the issue and run windows_detect_hung_tests.ps1 against the three named .cpp.tmp.exe tests on Win BMG with driver 101.8860. Compare the hang behavior across the affected tests and record whether the tests complete or remain blocked, with enough environment details to distinguish a test issue from a driver issue.
